  • Patent number: 11965174
    Abstract: Adeno-associated virus (AAV) Clade F vectors or AAV vector variants (relative to AAV9) for precise editing of the genome of a cell and methods and kits thereof are provided. Targeted genome editing using the AAV Clade F vectors or AAV vector variants provided herein occurred at frequencies that were shown to be 1,000 to 100,000 fold more efficient than has previously been reported. Also provided are methods of treating a disease or disorder in a subject by editing the genome of a cell of the subject via transducing the cell with an AAV Clade F vector or AAV vector variant as described herein and further transplanting the transduced cell into the subject to treat the disease or disorder of the subject. Also provided herein are methods of treating a disease or disorder in a subject by in vivo genome editing by directly administering the AAV Clade F vector or AAV vector variant as described herein to the subject.

  • Patent number: 11891619
    Abstract: Provided herein are adeno-associated virus (AAV) compositions that can restore F8 gene function in a cell without co-transducing or co-administering an exogenous nuclease or a nucleotide sequence that encodes an exogenous nuclease. Also provided are methods of using the AAV compositions to correct an F8 gene mutation and/or treat a disease or disorder associated with an F8 gene mutation. Packaging systems for making the adeno-associated virus compositions are also provided.

  • Patent number: 11833226
    Abstract: Novel adeno-associated virus (AAV) vectors in nucleotide and amino acid forms and uses thereof are provided. The isolates show specific tropism for certain target tissues, such as blood stem cells, liver, heart and joint tissue, and may be used to transduce stem cells for introduction of genes of interest into the target tissues. Certain of the vectors are able to cross tightly controlled biological junctions, such as the blood-brain barrier, which open up additional novel uses and target organs for the vectors, providing for additional methods of gene therapy and drug delivery.

  • Publication number: 20220389361
    Abstract: A cell cultivation apparatus for cultivating microorganisms and growing cells at high density is provided. The apparatus includes a membrane comprising multiple surface features on a first side of the membrane for cell placement. The surface features comprising one or more compartments within which a cell can be located. The membrane includes a material that is at least partially permeable to gas. A second side of the membrane defines a gas region. The second side of the membrane is separated from the first side of the membrane by the membrane. The apparatus further includes a media region for receiving media. The compartments are configured to at least partially reduce media flow shear forces on one or more cells in the compartments. The surface features may be ridges, protrusions, fins, wells, and/or posts.
